Well it has been three days now and the Fluidmaster is quiet and working. Weird that thwo different Korky towers didn't work and one new cap. Korky's are around $13 and Fluid master is around $7.90. Hm?
The only thing about the Fluidmaster is that the tower part it isn't tall enough. My tank is probably 40 years old, is taller than the new ones and holds more water. The Fluidmaster will only allow water to fill to with in two inches of the water line. I have the setting to maximum float height.
Oh well, it flushes fine and I'll save a bit more water. It'll help make up for the $100 that the Korky wasted.
